. 9 To all whom itmay concern:

Be it known 'that I, J ULES OLIPFEL, a citizen of the French Republic, and resident of Maub euge, in the North Dep artment,-France, have invented certain new and useful Improvements in and Relating to Multiplex Presses, of whichthe following is a specification. V

This invention relates to presses and especially to multiplex presses driven by power,

the object of this invention being to provide a press of this kind comprising a plurality of rotatable tool carriers, carrying each aplurality of working tool sets.

Another object of this invention is to provide a press of thiskind carrying at one end two simultaneously working tool sets.

Still a further object is to provide a ma-- chine of this kind wherein an automatic disengaging device is provided for the working tools and whereinone ,ormore of'the tool holders are extensible, these extensible tool holders being provided with an automatic actuating and reversing device as well as with a device for automatically stopping thaction of the said extensible tool holder.

With these objects in view myinvention consists in the combination of parts and details of construction hereinafter described and especially pointed out in the appended claims.

In the annexed drawings" in which similar reference numerals, designate corresponding. parts throughout several figures, Figure 1 is a general side elevation view of the machine certain parts being shown in cross section, Fig. 2 is a top plan view of the machine.

My improved multi'pleaction press comprises a main framework formed by an upper part 3 and a lower part 4 rigidly connected to one another by means of connecting staybolts 1 and 2. Adapted to be rotatedround these two bolts- 1 and 2 are two smaller frames 5 and 6 which carry allthe tools the movable as well as the stationary ones which are necessary for the works to be performed by the machine or press. i

The upper part 3 of the main'framework carries the presslevers -7, 8 and 9 adapted to oscillate each around a suitable shaft10,;11 and 12. The said press levers 8 and 9 are each provided at their upper part with two curved slots 14 and 13 respectively as well'as with an abutment 15 and 16. The hub of each of the levers is provided with a prismatic'connecting member 17, 18, 19 respectively adapted to connect the levers with claw couplin boxes 20, 21, 22 adapted to slide verticalfy in the upper frame 3 and to recpive the heads of the corresponding upper too s.

1 Connecting rods 23 and 24 connect the levers 8 and 9 withthe crank in 25 which is secured to the driving toot ed wheel 26 ada ted to rotate round a shaft 27. This toot ed wheel receives a continuous rotary motion from a series of intermediate gearings such as 28, 29 and 30 actuated by a belt pulley 31 provided with a flywheel, or by any other suitable power transmitting device. The connecting rods 23 and 24 are each provided at their ends which are pivotally connected with the press levers, with a couplin pawl 32, 33 the latter being each provide with a handle 34, 35 and a pressure spring 36, 37 acting on suitable flat parts of the connecting bolts 38 and 39 respectively. The said pawls are adapted to oscillate on the corresponding connecting bolt 38 and 39 respectively the ends of which slide in the said slots 13, 14. .40 is a link pivotally connecting the two press levers 7 and 8. A device arranged on shaft 41 and provided with a crank and abutment 43 constitutes the automatic disengagingdevice. 44 is a handle allowing of the device being actuated by hand. 45 and 46 are locking bolts adapted to rigidly connect at the re uired moment, the framings 5 and 6 with t e main frame work. One of the movable framings for instance 5 may contain one or more extensible tool carriers. Such an extensible tool carrier is. composed of a sleeve 47 whereto the working tools are secured. A vertical guide key 48 as well as an abutment 49 are provided on the said sleeve in which is equally screwed a screw 50 rigidly secured to a toothed wheel 51. A spring controlled buffer 52 tends to constantly hold in a raised position the whole extensible tool carrier. The toothed wheel 51 is actuated by a second toothed wheel 53 supported in the framing 5. The said toothed wheel 53 is provided with a'slot engaged by a rib of a coupling member 55 secured to shaft 54 which is journaled in a lateral bracket of the upper framing3. Secured to the same shaft 54 is a double bevel gearing 56 adapted to be actuated alternatively by two bevel gear wheels 57, '58 having difierent diameters and to each of which is rigidly secured a ratchet wheel.

The said driving bevel wheels rotate freely with the ratchet wheels on'a horizontal shaft 59. On the same shaft freely rotates a crank 60 which is provided with a pawl 61 controlled by a pressure spring 62. A link 63 hingedly connects the crank 60 with the oscillating lever 9. The pawl 61 is engaged in a fork 64 which is adapted to oscillate round a stationary bolt 65. The opposite end of the fork 64 is engaged in an oblique slot 66 arranged in a vertical disengaging rod 67, carrying at its lower end adjustable abut ting rings 68, 69. A third adjustable abutting piece 70 secured to the upper end of the rod is adapted to strike against a laterally yielding lever 71 which is fulcrumed at 73 on the framing 3. This lever 71 is adapted to engage a bent rod 72 secured to the pawl 33,

and to thus disengage the latter when the said lever 71 is raised by the rod.

The operation of the machine is as follows: The rotary motion of the crank pin 25 is con-. verted by the connecting rods 23, 24 into a reciprocating oscillatory motion which is transmitted to the levers 8, 9 and from the lever 8 to the lever 7 by means of the link 40, The said levers convert their motion by the intermediary of the links 17, 18, 19 into a vertically ascending and descending motion which is transmitted to the tool holders. When it is for instance desired to stop the motion of the tool holders on the side of the framing 6, the abutting piece 43 of the disengaging device is brought, by means of the handle 42, into the way of the crank 34 of the pawl 32 so that the latter is lifted and held stationary in its position by the spring 36 acting on a corresponding flat of the bolt 38. Consequently this bolt 38 of the connecting rods slide freely in its slots. When the abutting member 43 has been brought back into its upright position, shown in dotted lines in Fig. 1, the disengaging operation evidently does not take place and the motion of the tools takes place in an uninterrupted manner. The reengagement of the raised pawl is effected by hand and at will.

The operation of the extensible tool carrier is as follows: After the lever 9 has performed an oscillation corresponding to the descending stroke of the tool carrier 47 it returns and again begins to raise the claw coupling boX 22. However the sleeve 47 is held down by the tool being engaged into the block to be worked and the pawl 61 entering into action at this moment raises the screw 50' to a suitable extent. As a matter of fact at the very moment, at which begins the backward motion of the lever 9 the said pawl 61 is moved forward by the said backward motion of the lever 9 by the intermediary of the-link 63 and the crank 60. The said pawl 61 is engaged in the teeth of the ratchet wheel of the small bevel gear 58 so that motion is transmitted to the latter and therefrom by the intermediary of the toothed wheel 53 engaged with the toothed wheel 51. Thus the screw 50 is unscrewed from the sleeve 47 and is consequently adapted to follow alone the ascensional motion of the coupling box the sleeve and the tool being as stated held below. After a certain number of such working periods during which the sleeve is more and more lowered. at each stroke, the abutting member 49 of the sleeve finally strikes against the suitably adjusted ring 68 of the rod 67. The latter therefore also lowered and causes by the intermediary of slot 66 the fork 64 to oscillate so that the pawl 61 is engaged into the teeth of the ratchet wheel of the large bevel gearing 57. During the following ascensional motion not only the sleeve is carried on but at the same time also the screw 50 is rapidly screwed again into the sleeve 47 owing to the very quick rotation of the toothed wheel 5].. The said screw is thus brought back rapidly into its initial position. At the end of the rising motion of the sleeve the abutting piece 49 of the latter abuts against the ring 69 of the rod 67 thus raising the latter so that the pawl is pushed back on the teeth of the ratchet wheel of the bevel gear 58. At the same time the lever 71 is actuated by the abutment 70 which raises the pawl 33 of the connecting rod so that no further motion is transmitted until the pawl 33 is again engaged by hand, whereafter the same motion as above is repeated.
